What are messages?

A user or an app can send a message either to another user or to a group. One can send both plain text messages and messages with rich content. Plain text messages display the sender name, the user avatar, the text of the message, and the time at which it was sent.

On the other hand, messages with rich content (formally referred to as attachments) can show widgets, FlockML, images, buttons, and provide files to download, among other things. See Sending Attachments for more details.

What can I use Messages for?

Send notifications to a user or a group e.g. the ToDo app sends a notification whenever a ToDo is added, updated or deleted in the group.

Converse with your users using your app's bot. For eg the Reminder app bot sends a message to a user based on the user's configuration

Directly to a user from your app's Bots. This message will appear in your Bot's chat tab for that user. You may wish to do this for messages that are meant only for a given user e.g. the Reminder app bot sends a notification directly to a user
